What is muscle elasticity? If you were to stretch a muscle you would see it shrink back a bit. In plain words, it’s a natural ability to recover to original form upon the removal of the force initially applied. In physical activity it is the ability of muscles to perform work, specifically, to contract rapidly after and immediately prior to extension. A human body is a mix of physics, geometry, psychology and all that good stuff, so we should not talk about muscles and their function as separate from the whole. Muscles are a part of our entire system, and…

The original article (below) on the topic at hand, was published in Biomechanics of Distance Running in 1990. As you read the data and conclusions from this research you’ll see that the scientific community was not ready to accept the idea of the role of gravity as a leading force in running. A classical vision of gravity strictly as a vertical force was predominant in the scientists’ minds and didn’t allow them to look at the facts from a different perspective. The most important thing there, a relationship between extensor muscles and gravity as one non-conflicting system with reciprocal coordination…
